London dispersion force Subject

The interfacial tension between two phases is subject to the resultant force field made up of components arising from attractive forces in the bulk of each phase and the forces, usually the London dispersion forces, operating accross the interface itself (Fowkes, 1965 Adamson 1990) (see Appendix, this Chapter). 

By time averaging Ej t> nt>, the London dispersion energy is obtained. Recently a book on the theory of intermolecular forces that treats the subject in a comprehensive manner [153] has been published. 

A more vital application is to discern how reinforcement surface treatments improve adhesion to thermoplastic matrices. Since the nonreactive nature of thermoplastics normally precludes interfacial covalent bond formation, secondary bonding forces, such as London dispersion interactions and Lewis add/base interactions, may play a major role in these drcumstances. These secondary binding forces are subject to surface energetics analysis.
